Altair Multiscale Designer 2020 Release Notes
New Features
- Auto Calculate Bounds and Weights
- New options have been added to the Preferences dialog to enable auto
calculation for various entries based on “basic” user input
including:
- Linear Material Characterization
- Auto calculate weights
- Auto calculate bounds (%), user-defined percent
- Auto calculate tolerances (%), user-defined percent
- Nonlinear Material Characterization
- Auto calculate bounds (%), user-defined percent
- Auto calculate tolerances (%), user-defined percent
- Linear Material Characterization
- Support for New OptiStruct Multiscale Designer Interoperability Card MATMDS
- OptiStruct has added a new card MATMDS to facilitate easy inclusion of Multiscale Designer material models within OptiStruct. The new MATMDS card enables any Multiscale Designer material model to be referenced directly via an ASSIGN card. The location to the Multiscale Designer DLL is automatically located by OptiStruct. The MATMDS card is fully supported in HyperMesh v2020, so Multiscale Designer material models can easily be included in your OptiStruct modes via HyperWorks with zero deck editing. In addition, multiscale results are annotated with proper names (i.e. Fiber e11, Matrix Eq Plastic Strain, etc.) in HyperView, so the user no longer has to reference a SDV # to know what the result is.
Enhancements
- Abaqus *HOURGLASS STIFFNESS and *TRANSVERSE SHEAR STIFFNESS Support
- When exporting a Multiscale Designer material model to Abaqus, the *HOURGLASS STIFFNESS and *TRANSVERSE SHEAR STIFFNESS cards are now calculated and exported.
- Constituent Material Database
- The Constituent Material Database dialog window now remains active on the selection of a constituent material, so that review of the selected material can be accomplished easily, and/or the selection of another constituent material can be performed. To dismiss the Constituent Material Database dialog window, click close; otherwise, the dialog window remains active for as many user selections as desired.
- Multiscale Material Database
- The following Multiscale Designer multiscale material models are now
included and validated against the NIAR NCAMP/AGATE available material
data:
- AS4/8552 Unidirectional and Weave
- IM7/8552 Unidirectional and Weave
- T700/2510 Unidirectional
- T700/E765 Unidirectional
Resolved Issues
- The rotation matrix for calculating homogenized Coefficient of Thermal Expansion (CTE) values in Linear Material Characterization was resolved.
